CULINARY GRATER AND-SLICER.

SPECIFICATION forming part of Letters Patent No. 544,807, dated August 20, 1895.

Application filed December 5, 1894:. Serial No. 530,871. (No model.) I

To a/ZZ whom t may concern:

` Be it known that we, JOSEPH C. GROTE, a resident of Covington, in the county of Kenton and State of Kentucky, and PHILIP A. DOBERT, a resident of Cincinnati, in the county of Hamilton and State of Ohio, citizensof the United States, have invented certain new and'useful Improvements in Culinary Graters and Slicers, of which the followro ing is a specification.

Our invention relates to kitchen implements i for grating vegetables-such as potatoes, turnips, dsc., or the kernels of nuts or other articles used in cooking-and also for slicing r 5 certain vegetables, such as string-beans.

The purposes and objects of the invention will be fully understood from the following description of the accompanying drawings, in connection with which the invention will be zo first fully described, and then particularly referred to and pointed out in the claims.

Preliminary to a general description it is well to state that a single standard is adapted to receive either the grating device or slicing z 5 device,thetwo beinginterchangeably adapted to fit the frame and receive the handle or crank by which the device is operated.

Referring to the drawings, in which like parts are indicated by similar reference-let 3o ters wherever they occur throughout the various views, Figure l is a vertical transverse sectional view of the device fitted to operate as a grater, the section being taken through line 0o wof Fig. 2. Fig. 2 is a View, partly in side elevation and partly in vertical section, taken through line y y of Fig. l. Fig. 3 is a side elevation of the slicerapplied to the frame or standard, the grating appliance being removed for this purpose. Fig. t is a 4o view, partly in axial section and partly in elevation, the sectional View being taken through line z e' of Fig. 3. Fig. 5 is an end view of the slicingfcylinder with one of the plates removed and the upper portion of the hopper broken away. Fig. 6 is an end elevation of the device fitted to operate as a grater, taken at a right angle to the view shown in Fig. 2 and looking at the right-hand end of said figure. Fig. 7 is an end elevation of the device with 5o the grater attachment removed and the Slicer attached. Fig. 8 is an elevation, looking at the opposite end of the view shown in Fig. 7,

with the lower portion of the frame broken away. y

Referring first to the device with the grating attachment applied, as illustrated in Figs. l,

2, and 6, A is the standard or support, which has cast integral with it a flanged annular disk tt, having two laterally-projecting bosses u. and d2, the axially-projecting boss a to 6o furnish a bearing for the shaft b of the grating-cylinder B. The boss n.2 (shown in Figs. 4. and 6) furnishes a bearing for the shaft of the slicing-cylinder, as will be hereinafter dedescribed. The standard A has also projecting from its lower end bracket-arms a3 and a4, in the lower one of which is pivoted athumb screw a6, the upper jaw o.s acting as a clamping-jaw to rest upon the top of the table or other support, the screw a5 clamping the 7o frame in place. 'lhegrating-cylinder B is v mounted upon the flanged disk b', which is 4which passes through the fiange of the hous` ing and is tapped into the flange of the disk a to hold the housing in place. The upper portion of the housing is provided with a cylindrical hopper orvfeedlspout c2, which is pro' vided with internal ribs c3, and D (shown in dotted line, Fig. 1, and in full line, Fig. 6) is a follower having radial grooves upon opposite sides to lit the ribs c3 within the feed-spout 9o orhopper c2. The lower edge of the follower D is curved to conform to the periphery of the grating-cylinder B.

A portion of the lower` shell or housing C is cutaway between its ends and the side Walls of the cut-away portion turned out-v wardly to form flange c4, which form locking ways or guides for the trough or dischargespout E, vwhich has inturned flanges e to interlock with the outturned anges c4 of the roo housing. V

If it is desired to grate vegetables-such as` potatoes, turnips, &c.-the vegetables are placed in the spout or hopper c2, the follower being placed over them. Then, one hand pressing on the follower, while the other hand operates the crank-arm F, thevegetables are grated and the pulp passedthrough to the interior of the gratingcylinder B. If is desired to press the juice out of the grated pulp, the vhandle is held rigidly with the hand, while the juice may be pressed out through the openings in the grating-cylinder into the trough or spout E, or the pulp with the juice in it may be removed from the interior of the cylinder without expressing the juice.

The grater is also especially adapted for grating almonds or the kernels of other nuts, the desired quantity being placed in the hopper c2 and pressed down to the grating-cylinder by the follower D.

To remove the grating appliance from the standard A, the binding-screw c is first removed, when the housing with its attached gutter E may be taken ofi". The set-screwf is then turned back, the crank-handle removed from the shaft Z9, and the grating-cylinder withdrawn. The standard is then vadapted to receive the slicing attachment,

which will now be described.

The slicing attachment consists of the knifecylinder G and the grooved cylinder H, the two cylinders being journaled in bearings in the end plates I and J, held together by four staybolts t' and i. The plateJ has a shaftj extending rearwardly fromits centerto enter the boss a. of the standard A. The rear end of this shaft is transversely gained to furnish a seat for the screw j', which is tapped through the boss and enters the seatin the shaft or shankj to hold the cutting attachment rigidly secured to the annular disk a of the standard. The knife-cylinderG consists of the central shaft g, one end of which passes through the plate J andthe boss d2 and protrudes beyond the boss to receive the crank-arm F, and the opposite end of the shaft having a reduced neck g', which passes through the plate I, the tianged sleeve g2, which is held upon the shaft g by a screw-threaded connection, the cylindrical cutting-blades g5, which pass over the sleeve g2, the interposed washers g4, and the nut g5, which compresses the knives between the washers and the flanged end of the sleeve g2 and holds them rigidly in position. The cylinder H, which is of soft metal, preferably zinc, is secured upon the shaft h, which has its bearingsin the plates I and J. This cylinder is grooved to receive the cylindrical cuttingknives g3. The hopper K is mounted upon a plate 7c, which has its ends turned around in eyes 7c', through which the bolts z' pass to lock the hopper and its plate securely above the cylinders G and H. The plate 7c has its op-` tables longitudinally or in strings the articles are fed into the hopper K vertically, while if it is desired to cut them into short pieces they are fed in angularlywith one hand, while in either case the crank-arm is turned to operate the slicing-cylinders by the handlef. The cutting-blades g3 are'shown detachably secured upon the sleeve g2 by the interposed washcrsg4 and nut g5 in order that the blades may be removed from the shaft, if desired, for the purpose of sharpening them; but it would be an inferior modification of the invention to make the cutting-cylinder with its vbearings and knives integral instead of detachably connecting the knives to the cylinder, as shown, and the grooved cylinder, which is shown of a single piece grooved and secured upon its journal, may be made of separate disks with interposed washers, so that they may also be made to be detachably held upon the shaft, if desired.

It is also obvious that there may be many merely mechanical changes made without departing from the spirit or scope of the invention. Hence,

`Without limiting ourselves to the specific details of construction shown, what we claim as new, and desire to secure by Letters Patent, is-

1. The support for a culinary grater and slicer substantially as herein before set forth, which consists of the standard, A, having at one end a clamping attachment to be fixed to a rigid support, and at the opposite end a flanged disk having projecting from it two perforated bosses, one to receive the axis of the grating cylinder and the support for the cutting attachment, and the other one to receive the journal of the slicing attachment.

2. The combination of the standard, A, adapted to be secured to the support and having a flanged disk, a, and protruding bosses, a and d2, the slicing attachment consisting of the slicing cylinder, Gv, and grooved cylinder, I-I, the plate, J, having rearwardly projecting shaft, j, to enter the boss, at of the support, to furnish journals for the slicing and grooved cylinders, the plates, I, journaling the slicing and grating cylinders, stay bolts for holding the plates, I and J, together, the set screw for holding the slicing attachment in position, and the crank shaft for revolving the slicing cylinder, substantially as shown and described.

3. The supporting standard for the slicing and grating attachment, having perforated bosses to receive `the driving shafts of the slicing and grating cylinders, in combination with the grating and slicing cylinders,adapted to be detachably connected to said standard and interchangeably used with the same, substantially as shown and described.
